oven s Application filed Illecember 21, 1925.

lily invention relatesto improvements in means for operating easementwindows; that wi udows hinged at one side and opened. and shut by a swinging movement about an 2 's which is usually vertical, although not necessarily so.

To maintain such a window in any position oi" adjustment when open, and to hold it shut,

it has been the PlZlCLlCU, in some cases, to pro vide an actuating ine nber secured to the win dow sill near one side of the window, said tor. El uch niovelnent not reversible that is,

the window is held in any position, whether open or shut, and cannot be moved except by operating the worm and. gear by means of the handle. l Vhen the window sill on which. the adjuster is installed. is not horizontal, or where after installation said window-sill bocouies warped, or where the windowatraiue itself becomes warped, the vertical. axis of the sod "ing rod does not remain parallel to the axes oil the window hinges, and, as a result, the rod. binds when the window is partially open, an d such binding may prevent opening; the window 'lully.

'ihe object of this invention is to provide .uieans for compensating for .irre gulai 'tics in the iuoven'ient oi? the actuating rod with respect to the window, or vice versa, whereby said window may be opened and closed, without binding.

in the accou'i ianying drawings, l; have shown several embodiments of my iuventiini.

frame 1 having the usual sill 2 in any suitable form, with the window-sash 3 hinged to the winrlcii'aliraine at one side thereof, one of the hinges being shown at t. A housing or casting 5 is mounted on the window-sill, located preferably at the side near the hinge l, and being secured in place by screws 6, or other suitable fastening means. lhe housing providcs abearing for a shaft 7 having a worm 8 thereon which meshes with a gear sector 9, the latter being mounted to turn about a vertical shaft 10. A rod 11 is secured at one end to said gear sector and when. the window is closed is arranged as shown in Fig. 2, nearly parallel to the lower sash otthe whidow. {laid rod may be oi? any suitalrile cross-see tieual outline, but preferably round and passes through a circular opening 12 in a link Iii-s, said li it being pivoted at 14; to a bracket coiuprisiuga pair oi? angles secured to said sash.

'lhe free end of said link may thus swing up and down in a vertical plane about the horizontal pivot lei. lhe opening 12, as shown in Fig. l, is provided nrciierably with a beveled edge lo so that the contact between the wall of said opening and said rod is confined almost to an ed e, thus permitting; a deviation of the rod. 11 an a position at right angles to the plane oil? the opening without causing biudmg. l

by suitable liorin oi? handle li' may be provided l'or rotatuu; the sha'ltt 'Z' and. thus cause the rod ll to st .1 g in a substantially horizontal 3 e atoutits vertical shafhand thus swi the easement window about the vertical. axes airlorded by the hinges. The en.- gggau'enient oil the gear sector with the worm results .111 holding the window in any position in which it may be left; that is partially opened, :lully opeiiied, or completely closed. ll the wiudow-sill 2 is horizontal at the time oi. installation and the window-frame and. sash are accurately made, the vertical axis about which the rod ll swings will be CX- actly parallel with the vertical axis about which the window swings. However, if the window-sill is not horizontal, as is frequently the ca so, or iii? it sul'isequently warps, or the wi'udow-iran'ie warps, the window hinges may be thrown out oi? aliueinent or the housing); 5 may be tilted from a horizontal plane, whereby when the window is swung; open, ninety degrees for example, the rod 11. :insread'oi being horizontal will slope downmay deviate from its initial swinging movement. To prevent the binding between the rod 11, and the co-operating parts secured to the. window-sash, the previously described two-part construction 13 and 15 is employed, whereby the link 13 may swing upwardly or downwardly to whatever extent is necessary within reasonable limits, to accommodate the irregularity in the movement of the actuating device, or of'the sash itself.

7 In Fig. -7, I have shown how the link 13 swings downwardly, even to a. position below thefnormal'level of the window-sill, in e:-:- trenie cases. p Y

In Fig. 5, I have shown a modification oi the link 13 in which the opening is provided with a bushing 18 having a rounded inner surface to prevent binding of the rod in different angular positions therein.

In Fig. 6, a further. modification is shown wherein a supporting bracket 19 has a rivet 2O therethrough constituting a vertical beau V ingahout which :1. depending U-shaped member 21 maytu'rnp llhe downwarr ly extend ingarms engage opposite sides of th actuating rod andpermit a'certain up and down movement thereof without disengagement of the parts, the U-shaped member turning back or forth'to whatever extent is necessary as the window swings to different positions of adjustment. While this modification has been used satisfactorily, it has limitations in that th'e'downwardly extending arms cannot be too long or they will strike the window-sill.

when thewindow is closed and-under extreme conditions of warping may not be long enough'to insure engagement with the actuating rod when-the window isopened. The

lower part of the sash on some windows is quite narrow, thereby limiting the available space in which the bracket 19 may be secured.

at is, in some cases, it cannot be secured high enough to permit the arms 21 to be made long'enough to meet extreme conditions. For

, this-reason, the forms shown in Figs. 4 and 5 are the preferredones, wherein the link 13 may be made long enough and'swing up and down far enough to remain operative under extreme cond tions of warpin said link also being restored to its normal position when the window is shut, whereby it clears the window-sill. even though it is not mounted 7 very high above the same.

Innormal position, the bracket 15 is slightbracket having means for ly higher than the rod 11, as shown in Figs. 1 and 3, to facilitate installation thereof without too much interference by the rod 11 with the screw-driver or other tool which may be used. The gear sector 5) may be provided with a pin or stop 22 which engages the worm when said sector has rotated the desired amount, thus preventing opening the window beyond a ninety degree angle, or to whatever angle may be desired.

Although the invention has been described in connection with means for swinging a w' idow about a vertical axis, it is obvious that it is not limited to windows ol this QM]- eral type, but may be employed in connection with other types of windows or ventilators turning about any axis, whether vertical, horizontal or inclined.

What I claim is:

1. In a device of the class described, a

window, a link secured to said bracket by means of a horizontal pivot. whereby said link may swing in a vertical plane, said link having an opening therethrough with a bev eled edge, a rod passing through said open ing and conforming in cross-sectional outline thereto, a pivotal support at one end of said rod, and means for causing said rod to swungabout its pivot and open and shut said window, said link compensating for rrcgniarities in the movement of said rod with rolei'eice to said window and without binding.

2. A device of the class described comprising a bracket adapted, to be secured to a hinged window, a housing secured to a stationary support inwardly of said window, a rod pivotally secured to said housing on an axis normally parallel to the axis oi the wiudow hinge, manually operable means carried by the housing for swinging said rod upon its pivot and means for transmittin met". from the rod to the bracket for operating id window without binding. said means comprising a member pivoted to said bracket and having a passage through which the rod extends for accommodating movement of the :iVOtfll axis of said rod out of parallelism with the window hinge and varying: angularities ofthe rod with respect to the window during the opening and closing, oi the latter.

In testimony whereof, I have subscribed my name.
